[PATCH v4 12/12] tests/migration-test: Add a precopy test for guest-memfd

From: Peter Xu <[email protected]>

Add a plain tcp test for guest-memfd.  Note that the test will be
automatically skipped whenever not supported (e.g. qemu compiled without
KVM, or host kernel doesn't support kvm, or old kernels, etc.).
